7 key lessons from Buffett that can help you become a better investor:

Warren Buffett is one of the World's most successful investors (with a net worth of over $100 Billion), and has shared his investing wisdom through his annual letters. Here are 7 key lessons from Buffett that can help you become a better investor:
1) MOATs:
A moat is an economic advantage that a company has over its competitors. It can be anything from a strong brand name to a patent.
Moats are important because they protect companies from competition and allow them to earn higher profits.
2) What you own matters so focus on businesses:
Buffett focuses on businesses with great management and economic advantages.
He calls himself a "business picker," not a "stock picker."
3) Market pricing is irrelevant in the long term:
Buffett says that a stock price shouldn't determine whether you buy or sell.
In the short term, people vote with their dollars on which stocks will do well.
But in the long term, stocks with the most value tend to do well, regardless of their price.
4) Adopt a patient investment approach:
Buffett says that "for investors as a whole, returns decrease as motions increase."
This means that the more you trade, the less money you're likely to make. The best investors are the ones who buy and hold for the long term.
5) Time is a friend of great businesses, but an enemy of the mediocre:
Great businesses tend to get better over time, while mediocre businesses tend to get worse.
This is why it's important to invest in great businesses and hold them for the long term.
6) Be greedy when others are fearful:
When the market is down, that's when you should be buying.
This is because great businesses are often on sale when everyone else is panicking.
7) Rebalance your portfolio, but don't sell your winners:
Rebalancing your portfolio is important, but you don't want to sell your winners just because they've gotten too big.
Instead, you should sell your losers and use the proceeds to buy more of your winners.
